5. If required (to provide more space), temporarily remove the front system fans from their slots in
the bottom fan holder foam. (Do not disconnect the fans’ power cables.)
6. Reach your fingers between the fan holder foam inside the server and the hard drives and
carefully disconnect the power and signal cables for both hard drives.
Note: If you are able to disconnect the cables for only the hard drive you want to remove, that
is acceptable. You may find it easier however, to disconnect the cables for both hard drives.
7. Pull the drive carrier out of the chassis, and then place it cage-side-up on an antistatic surface.
8. Continue with “To install a new hard drive in the drive carrier” below.
To install a new hard drive in the drive carrier
1. Remove the new drive from its protective wrapper, and place it on an antistatic surface.
2. Record the drive model and serial numbers in your equipment log.
3. Set the hard drive settings as described in “Hard drive configuration” on page 112.
For instructions on changing the hard drive’s settings, refer to the drive manufacturer’s
documentation.
4. If you are replacing an existing hard drive, remove the old drive from the drive carrier as
follows:
a. Remove the four screws that attach the drive to the carrier.
b. Lift the carrier off of the hard drive.
c. Place the drive in an antistatic protective wrapper.
5. Position the new drive component-side down inside the drive carrier, and then attach the four
screws that you removed earlier.
Ensure that the connectors on the back of the drive are flush with the rear of the drive carrier.
6. Continue with “To install the hard drive” below.
To install the hard drive
ATTENTION
The last bay must remain empty to ensure proper system
cooling.
1. Slide the hard drive and drive carrier assembly (with the exposed drive facing up) into the
server bay.
ATTENTION
To provide more space inside the server so that you can
connect the cables,
do not push the drive all the way in (that
is, until it clicks into place).
2. If not already done: Temporarily remove the front system fans from their slots in the bottom fan
holder foam.
Do not disconnect the fans’ power cables.
3. Connect the hard drive’s SCSI cable as follows (the end of the cable with two connectors is the
hard drive end):
a. Ensure that a terminator is connected to the last connector at the hard drive end of the
cable.
b. Connect the second connector on the cable to the hard drive.
Place one hand on the front of the hard drive to hold it in place while you connect the
cable with the other hand.
